Title: Digital controller
Inventor: KADOHARA HOZUMI
IPC: G06F11/20
Filed: 1997-06-24
Abstract: PROBLEM TO BE SOLVED: To omit the transfer of input data between two systems and also to maintain the control of an object with no sudden change of the control data when one of both CPU parts (A and B systems) has a failure and then the faulty system is switched to the other normal system to carry on the control. SOLUTION: Both A and B systems 17 and 18 receive the input signals and the operation signals from a plant equipment system 50 and an operator station 10 respectively and always perform the same control calculations. For instance, the systems 17 and 18 are set in a control state and a standby state respectively. Then the system 17 outputs the control calculation result and the system 18 outputs no control calculation result. When a self-diagnostic means 171 detects the failure of the system 17, the system 17 is switched to a fault state from its control state. Meanwhile, the system 18 is switched to a control state from its standby state. As the systems 17 and 18 are always performing the same control calculations, no transfer of input signals is needed between both systems together with no sudden change of the control data. Thus, the stable control is maintained for a control object.

Filed: 1983-09-13
Abstract: PURPOSE:To simplify the titled measurement by feeding powdery granules of a sample into a vessel maintained at a fixed temp. and packed with a gas of known pressure and humidity, and measuring increases in pressure and volume of the gas in the vessel. CONSTITUTION:In case air of known humidity is fed into the vessel whose temp. (t) deg.C is kept constant, the pressure is denoted as P. It is assumed that the pressure becomes P+DELTAP, and the vol. of the gas varies to v+DELTAv from v. If a saturated vapor pressure at (t) deg.C is denoted as (es), a partial pressure of vapor in air of known humidity as (e), a relative humidity H of the air in equilibrium with the sample powder granules is known as H=(100/es)[e+DELTAP+P(DELTAv/v)] by calculation. Then, by the humidity of the air in equilibrium with the sample powdery granules is known by measuring DELTAP, DELTAv, the moisture thereof is known, thereby, the measurement can be simplified.

Abstract: PURPOSE:To simplify a correction of a character train, by providing a specific key which can select a means whether an input character is put after a prescribed character or superposing the input character on the prescribed character when a correction is given to a character train. CONSTITUTION:A cursor is set on a display device 94 and at the position where the insertion of a character is desired, and an INSERT key is pushed. Thus a lamp glows to show that the character is being inserted. Then a desired character is inserted by pushing continuously the corresponding input key. When the INSERT key is pushed after the insertion of the character is over, the lamp is turned off. In such way, the INSERT key is pushed every time the insertion of a character starts and ends. The character corresponding to an input key is fitted to the registered cursor position of a memory if the key is identical with the character to be inserted. Then the subsequent characters are all shifted to the right by one character.
